9 Claims.

This invention relates to' a siding unit and asmore, such thin sheets, at their overlapping portions, may permit vibration or may rattle undesirably when the assembly of the sheets is struck these composition sheets are ordinarily superficially wettable by water.; the water may be drawn upwardly between the joints of overlapping units.

It is an object of the invention to provide sid- 20 ing units and an assembly thereof that overcomes one or more ofth'e above objections to such units or construction. Other objects and advantages of the invention will appear from the 4 detailed description that follows. g5 The invention comprises the novel features of the individual units or assembly thereof that are herein described or illustrated. In a preferred embodiment, the invention comprises means for concentrating the pressure of an overlapping zo portion of a side unit against a lower course of the units, 'in a single narrow zone. The invention comprises, also, `means associated perma- 'nently with the side of one of the said sheets, for displacing outwardly the portion of another er, sheet overlapping the said side portion and spac- I ing the said other sheet from the supporting substructure or from the plane of the main portion of the said one of the sheets; More specifically, the invention `comprises a siding unit provided 0 with a longitudinal ribbed side portion and an assembly in which a side portion of plane surface of another unit overlaps the said ribbed portion and contacts therewith along a relatively narrow zone. The invention comprises, also, an assem- -,A bly including vibration-damping material disposed in the joint between overlapping courses ofunits, terminating above the lower edge of the unit of the overlying course at the joint and being engaged, advantageously, at its upper portion .over the upper edge of a unit of an underlying cours'e. l

`The invention is illustrated in the attached drawing and will, be

' therewith.

55` Figs. l-6 Ashow sectional perspective views of lapping to form therebetween described in connection different embodiments of my improved siding units Aand the assembly thereof on the side of a building. Fig. '7 shows a modified unit.

There are shown parts of a building including a supporting substructure comprising, for exam- 5 ple, studs Il, wood sheathing I2, and, in one instance, units I3 such as old wooden shingles over which my new siding assembly is made.

My siding assembly includes a plurality of thin sheets, suitably asbestos-cement units, over- 1 joints extending horizontally, as illustrated in Figs. l-5, or extending vertically, as illustrated in Fig. 6.

The siding units that are preferred at this time are ,indicated by reference characters l I4-25, inclusive.

Each of these siding units I4-25 has a longitudinally ribbed marginal or edge portion and substantially plane surfaces on both faces or y sides. The units may be vapplied to the substruc- 20 ture, so that the ribs have their concave surfaces turned either forwardly or backwardly, that is, towards the outside of the wall or to. the rear thereof.

The ribbed portions contact each along a line 85 or narrow zone with the side portion of plane lsurface of an overlapping unit. Also, the rib extends backwardiy (Figs. 1A and 2) or forwardly (Figs. 4 to 6) from the plane of the main portion of the unit. l

Fastening means, such as the nails 26, secure the several units to the substructure. Because of the concentration of the pressure from the fastening means along the single line or narrow zone of contact between overlapping sheets, rat-` 85 -tling of the assembly at the joint portions, as well as entrance of air or rain, is minimized.

The sheets I4, l5, and IE in the embodiment of Fig. 1 are arranged in the assembly with the convex portions of the ribs depressed from the 40 plane of the main portion of the sheet, disposed in contact with `the supporting substructure, and servingY to space the said main portion of the sheets from the substructure. For sheets adapted to absorb an appreciable proportion of water, this spacing minimizes passage of moisture, through the sheets,`to thesubstructure. Considering unit I5, for instance, the upper edge of the ribbed portion contacts with the back of the lower portion, of plane surface, of a unit Il 5o of an overlying course in the siding assembly. Also, the unit I4 extends substantially below the upper edge of the ribbed portion of the lower unit, as illustrated at 21, with its lower edge substantially overlying the midportion of the 5I stance.

' again, the nails Vor other fasteners ribofthelmit I5. Theresultistheprovlsion ofafreespacebehindtheloweredge oftheunit I4 and attendant minimization of the tendency to the drawing of water upwardly behind the sheet Il and through the joint, by capillarlty.

Also. the extension of the sheet Il over a portion of the concavity in the rib of the sheet l5 increases the desirable shadow effect, serving the useful architectural purpose of providing im adequate shadow that is considered an essential feature of the colonial clapboard assembly, for in- It will be noted that the sheet Il in its full thickness extends over the upper edge of the bead and that the total displacement of -the face of the sheet Il, at its lower edgerfrom the material of the sheet I5, is substantially greater than the maximum thickness of the sheet I I.

It will be noted, also, that the main portions of the sheets Il, I5 and I6 extend substantially in the same plane, in spite of the provision of the desirable *type of joint described.

Fig. 2 illustrates siding units laid up in a manner similar to those of Fig. 1. In this embodiment, however, a layer of yielding backing mal is secured to the back of each of the units. 'Ihe backing material has one edge in substantial alinement with the mid-portion of the rib and its other edge in substantial alinement with the lower edge of the unit. When the units are assembled on a wall the lower margin of the backing material of each unit partially underlies a portion of the rib of a next lower unit in the manner shown.

In the sheets lI-ZS, inclusive, of Figs. 4 to 6 the ribbed portions are convex on their forward surfaces and either underlap or overlap portions of plane surface of adjacent sheets. Here 26 hold the sheets in tight contact, the pressure being concentrated along narrow zones.

In the structures illustrated in Figs. l, 2, 3 and 4, means permanently associated with one side of each of the units serve to displace the overlapping lower or side portion of the adjacent 'Il soolieoftheallpendedclanns.

unit away from the substructure, with attendant decrease in vibration or rattling tendencies, all as previously emphasized.

The modified unit shown in perspective in Fig. 7 has an irregularly extending edge 33 opposite the ribbed portion. 'I'he irregularities may take the form of waves, for instance. 'I'hey add to the architectural eil'ect by reducing the appearance of mechanical regularity of the assembly.

Fig. 3 shows a modified form of means 28 also permanently associated with the side portion of one of the units, as by the engagement of the shoulder or offset portion 2! over the upper edge 0f the said unit. A 'lhe member may be vibrationdamping and Aconstituted suitably of an asphaltimllregnated rag felt or the like of substantial thickness, say, V4 inch or more. A cork strip maybe used.

'Ihe main portion of the member 2l extends continuously withinthe joint between the overlapping units and terminates, at its edge 3l, above the lowest part or lower edge of the overlapping unit 3|, so that a free Space is defined between the said lower edge of the unit 3| and the unit 32 of an underlying course, for instance.
